Modeling 3D euclidean geometry [PDF]
IEEE Computer Graphics and Applications, 2003 This article compares five models of 3D Euclidean geometry-not theoretically, but by demonstrating how to implement a simple recursive ray tracer in each of them. It's meant as a tangible case study of the profitability of choosing an appropriate model, discussing the trade-offs between elegance and performance for this particular application.

Chronological sequence of megalithic burial complexes of the Eneolithic in the Velikaya Aleksandrovka burial mound [PDF]
Материалы по археологии и истории античного и средневекового Причерноморья, 2022 The emergence of the earliest burial mounds in the Eneolithic of the North Pontic steppes (3900/3800—3500/3400 BCE) was accompanied by the construction of the earliest megalithic structures — cromlechs, the circular structures of which consisted of ...

3D channel model in 3GPP [PDF]
IEEE Communications Magazine, 2015 Multi-antenna techniques capable of exploiting the elevation dimension are anticipated to be an important air-interface enhancement targeted to handle the expected growth in mobile traffic. In order to enable the development and evaluation of such multi-antenna techniques, the 3rd generation partnership project (3GPP) has recently developed a 3 ...

Progress in Biomedical Engineering, 2022 Abstract Glioma is one of the most malignant types of cancer and most gliomas remain incurable. One of the hallmarks of glioma is its invasiveness. Furthermore, glioma cells tend to readily detach from the primary tumor and travel through the brain tissue, making complete tumor resection impossible in many cases ...

Optimising Point Cloud to Wireframe Conversion for 3D City Modeling [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesUrban planning increasingly relies on structured 3D city models for analysis and decision-making, but while point clouds capture rich detail, their unstructured nature complicates direct use in CityJSON-based workflows.

A sketching interface for 3D modeling of polyhedron [PDF]
, 2006 We present an intuitive and interactive freehand sketching interface for 3D polyhedrons reconstruction. The interface mimics sketching with pencil on paper and takes freehand sketches as input directly.

1D Model for the 3D Magnetohydrodynamics
Journal of Nonlinear Science, 2023 We propose a one-dimensional (1D) model for the three-dimensional(3D) incompressible ideal magnetohydrodynamics. We establish a regularity criterion of the Beale-Kato-Majda type for this 1D model. Without the stretching effect, the model with only transport effect equipped with a proper sign is shown to have global in time strong solution.

Statistical modeling of facial aging based on 3D scans [PDF]
, 2010 This thesis presents an approach to the modeling of facial aging using and extending the Morphable Model technique. For modeling the face variation across individuals, facial expressions, and physical attributes, we collected 3D face scans of 298 persons.
